JAK2V617F Mutation Analysis, Quantitative, With Reflex to JAK2 Exon 12-15 Mutation Analysis by NGS
Use
Molecular testing of blood or bone marrow is useful in the evaluation of suspected myeloproliferative neoplasms (MPN). This test will assess for the JAK2V617F (exon 14) mutation first and will reflex JAK2 exon 12 to 15 mutation analysis if the JAK2V617F mutation is negative.
Special Instructions
Submit specimens at room temperature. Specimens should arrive in the laboratory within 48 hours of collection. Indicate date and time of collection on test request form. Store specimens at 2°C to 8°C if stored prior to shipment.
Limitations
This assay has a sensitivity of approximately 1% VAF for JAK2V617F and 2.5% VAF for other mutations in JAK2 exons 12 to 15. Deletions in JAK2 up to 6 bp and insertions up to 34 bp have been detected in validation studies. The test has not been cleared or approved by the FDA.
